Solution

The correct option is B Polytene
Polytene chromosomes are giant chromosomes commonly found in many dipteran (two-winged) flies. Drosophila is a genus of two-winged flies commonly known as fruit flies. Polytene chromosomes begin as normal chromosomes, but through repeated rounds of DNA replication without any cell division (called endoreplication), they become large, banded chromosomes.

So, the correct answer is 'Polytene'.
